I am upgrading a helper jar file that has some validation and configurations settings for a project. I am using spring-boot 3.2.5

<spring-boot.version>3.2.5</spring-boot.version>
<springdoc.version>2.5.0</springdoc.version>
<java.version>17</java.version>
<jackson-databind-nullable.version>0.2.6</jackson-databind-nullable.version>
<jakarta.servlet-api.version>6.1.0</jakarta.servlet-api.version>
<jakarta.annotation-api>3.0.0</jakarta.annotation-api>
<jakarta.el.version>3.0.3</jakarta.el.version>
<jakarta.validation-api.version>3.0.2</jakarta.validation-api.version>

It seems the generated Validation classes have changed. However I cannot seem to find the correct documentation supporting my assumption.

The pom.xml file was on spring-boot.version 2.5.2 and the main reason I need to update it is because the other applications that use this jar will soon be on spring 3 and that means no javax but rather jakarta imports.

The previous and upgraded openapi versions are below.

 <artifactId>openapi-generator-maven-plugin</artifactId>
 <version>5.3.0</version>

 <artifactId>openapi-generator-maven-plugin</artifactId>
 <version>7.6.0</version>

The openapi.def.json files are the same. What I am not sure about is if I am missing a dependency or if I need to adapt my openapi json files.

For example I have a openapi generated class I was using called QueryOptimization which is now not found. However the file QueryOptimization.def.json still remains and I do see a class generated called QueryOptimizationdef.

@Generated(value = "org.openapitools.codegen.languages.SpringCodegen", date = "2024-06-14T12:41:26.384867+02:00", comments = "Generator version: 7.6.0")
public class QueryOptimizationdef extends ConfigEntitydef {

What looks like happened is QueryOptimization name has changed to QueryOptimizationdef and some return types have changed to . But changing the class names and type set me on a path of changes all over.

Has anyone experienced this before? Is there a way to keep the class names the same? This would be a pretty large change and I am honestly not sure if my assumption is correct.
